  An example of a procedure for mounting the concealing member 80 will be described. 10 and 11 are diagrams for explanation. That is, first, as shown in FIG. 10, the upper part of the concealing member 80 is tilted so as to approach the swing frame 20. Then, as indicated by an arrow P in FIG. 10, the engaging piece 83 a of the lattice horizontal frame 83 is hooked on the lattice horizontal frame engaged piece 27 d of the swing horizontal frame 27. Thereafter, as shown by the arrow Q in FIG. 10, the concealing member 80 is brought into close contact with the swing frame 20.

  Next, by the rotation of the arrow Q, the lattice vertical frames 81 and 82 are brought into close contact with the swing frame 20 as indicated by Q in FIG. Then, the fixing members 86b and 86b are passed through the pieces 23b and 26b and screwed into the receiving members 86a and 86a to be fixed. At this time, the fixing member 86b extends in the expected direction and can be operated with a tool inserted in the expected direction. Therefore, the work is simplified.

  On the other hand, when removing the concealment member 80, the above may be performed retroactively. Therefore, not only the attachment of the concealing member 80 at the time of construction but also the subsequent attachment / detachment is easy.

  Next, the movement of each part when the upper door 30 and the lower door 50 are opened from the closed position will be described. 12 and 13 are explanatory diagrams. 12 and 13 are cross-sectional views in the vertical direction, respectively, (a) showing the posture of the upper shoji 30 and lower shoji 50, (b) showing the posture and position of the guide (38, 56, etc.). Yes. Although only the one guide rail member 26 side is illustrated here, the same applies to the guide rail member 23 side disposed opposite thereto.

  From the closed posture of the upper shoji 30 and lower shoji 50 shown in FIGS. 2 and 5, the gripper 53a provided on the upper lateral arm 53 of the lower shoji 50 is pulled to the indoor side as shown in FIG. . Here, since the latches 56, 56 are arranged on the upper part of the lower shoji 50, as shown in FIG. 12B, the latches 56, 56 move from the guide groove 26d to the indoor guide groove 26e. Can be made. As a result, as shown in FIG. 12A, the lower shoji 50 is in a posture in which the upper end is tilted to the indoor side.

  Here, even when the upper guide is a member that is manually slid instead of being latched, the upper portion of the lower shoji 50 is similarly brought down indoors by manually projecting and retracting the member, and the member is inserted into the guide groove 26e. Can be placed.

The lower shoji 50 is pulled up from the posture shown in FIG. Then, as shown in FIG. 13, the rotating lower guide 58 of the lower shoji 50 moves the guide member 58 c in the guide groove 26 e among the rotating lower guide 58. Of the rotating lower guide 58, the wire locking projection 58d moves in the guide groove 26d. Accordingly, the rotating plate 58b of the rotating lower guide 58 moves upward in a posture close to the horizontal as can be seen from FIG.
On the other hand, when the lower shoji 50 is pulled upward, the upper shoji 30 moves downward by its own weight so as to keep the balance through the wire 73. Thereby, as shown in FIG. 13A, the upper shoji 30 and the lower shoji 50 are in the open posture. Here, as can be seen from FIG. 13 (b), the rotary lower guide 58 has the wire locking projection 58 d pulled by the upper obstacle 30 via the wire 73, so that the wire locking projection 58 d is a guide. It moves up and down while maintaining a posture slightly above the member 58c.

  As described above, according to the opening device 1, the two shojis that move relative to each other up and down in conjunction with the wire can be arranged in the same plane when they are closed. This makes it possible to reduce the thickness of the swing frame 20 and improve the appearance when closed. Further, as can be seen from the above, the operation of opening the shoji is easy, and the mechanism therefor is also simple.

  Further, since the thickness of the swing frame 20 can be kept thin, a member protruding outside the swing frame 20 on the outdoor side can be made small, so the size shown by B in FIG. 2 is kept thin. Became possible.

Further, the rotary lower guide 58 also has a function of preventing “pinching” such that when the wire 73 is broken, the upper shoji 30 and the lower shoji 50 are suddenly dropped to the bottom, and something is pinched here. . An explanatory diagram is shown in FIG. In FIG. 14, similarly to FIG. 12B and FIG. 13B, the position of the shoji is shown by the position of the guide.
Consider a case in which the wire 73 is cut for some reason in the open posture of the upper and lower shojis 30 and 50 as shown in FIG. When the wire 73 is cut from the state of FIG. 14A as shown in FIG. 14B, the rotary lower guide 58 is not affected by the tension from the wire 73. As a result, the wire locking projection 58d is lowered to a position lower than the guide member 58c. Accordingly, the rotating plate 58b is inclined so as to be slightly below the outdoor side (A in FIG. 14B).

  Further, the shoji 50 is dropped at the position and posture of the rotary lower guide 58 indicated by A in FIG. However, due to the above-described posture of the rotary lower guide 58, the rotary lower guide 58 is caught between the straight portion 26e ′ and the inclined portion 26e ″ of the guide groove 26e and can move downward. Can not. Therefore, since the lower shoji 50 does not fall below this, “pinching” can be prevented.

  On the other hand, the upper shoji 30 cannot be lowered below the guide groove 26d because the wire locking projection 58d of the rotary lower guide 58 exists in the guide groove 26d. Therefore, it is possible to prevent the “paper jam” from occurring in the upper screen 30 as well.

  Thus, according to the rotary lower guide 58, it is not necessary to provide a new member as a safety device. However, this does not hinder the addition of other safety devices from the viewpoint of further improving safety.

  In the present embodiment, an example in which the above-described concealing member is applied to a raising / lowering shoji in which two shojis are opened and closed in conjunction with each other has been described. It is possible to apply also to the raising and lowering window.

  Although the present invention has been described in connection with the most practical and preferred embodiments at the present time, the present invention is not limited to the embodiments disclosed herein, The invention can be changed as appropriate without departing from the spirit or idea of the invention which can be read from the claims and the entire specification, and the opening device accompanying such a change should also be understood as being included in the technical scope of the present invention. I must.
